Topsheet of a diaper



The sole FIGURE is a top plan view of a topsheet of a diaper, showing our new design.

The grayscale shaded region within the broken lines represents the claimed design. The broken lines outside those surrounding the claimed design depict portions of the topsheet of a diaper that form no part of the claimed design.

The region disposed between the broken lines and the central unclaimed area, excepting the grayscale shaded region, also form no part of the claimed design. 

We claim the ornamental design for a topsheet of a diaper, as shown and described.
